WEATHER-STRIP.

Specification of Letters Patent.

Patented' Apr. 27, 1920.

Application filed March 16, 1917. Seria1 No. 155,298.

To all ful/tom t may concern:

Be it known that I, CHAnLEs H. STARK, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented new and useful Improvements in Weather-Strips, of which thefollowing is a specification.

The weather strip which is the subject matter of the present applicationfor patent is designed more particularly for sealing the joint between awindow and door frame and the masonry wall in which the frame is fitted.

The invention has for its object to provide a weather-strip of the kindstated which can be readily applied without altering or modifying thestructure to which it is applied, and which forms an effective seal.

The object stated is attained by means of a novel combination andarrangement of parts to be hereinafter described and claimed and inorder that the same may be better understood, reference is had to theaccompanying drawing forming a part of this specification.

In the drawing- Figure 1 is a perspective view of a fragment of thepacking strip, and

Fig. 2 is a horizontal section showing the strip in place.

Referring specifically to the drawing, the invention is shown applied tothe joint between a window or door casing and the masonry wall in whichsaid casing is fitted, but it will be understood, that the invention isnot limited to this particular application, but may with equal facility,be applied to other locations. The masonry wall is shown at 5, and thestile of the window casing at 6, the latter having the usual staff-bead7 on the outside which seats at its inner edges against the wall. rlheweather strip which is the subject matter of the present application isapplied to the joint between the abutting parts 6 and 7, and also wherethe wall abuts against the window casing.

In carrying out the invention there is provided a sheet metal base strip8 of suitable length according to the length of the joint, said stripbeing constructed to serve as a holder for two packing strips 9 and 10of felt or other suitable material usually employed for weather strips.The strip 8 is bent lengthwise to form an outstanding flange 11extending throughout the entire length of the strip, and the latter istherefore angular in cross section.

forming the wall.

The packing strip 9 is positioned on that side of the base strip 8 fromwhich the flange 11 projects and the packing strip 10 is carried by theflange. The packing strip 9 is secured at one edge by crimping orbending the marginal portion of the strip 8 over as shown at 12 totightly grip the same, and the packing strip 10 is secured to the flange11 by rearward and return bends 13 at the outer edge thereof, said stripbeing gripped between said bends. Thus, the two packing strips areoffset with respect to each other and the strip 10 is in advance of thestrip 9.

In applying the device, the strip 8 is placed. against the outside faceof the plank forming the stile 6 of the window casing so that the flange11 seats on the inner edge of the bead 7 projecting laterally from thestile. This is done before the wall 5 is run up. The packing strips 9and 10 face outward, and hence when the bricks or other building blocksforming the wall are laid7 the pack ing strips seal the joint betweenthe same and the parts 6 and 7 as shown in Fig. 2. The bent portion 18of the base strip is embedded in the mortar or other binding materialbetween the inner and outer bricks The joint is therefore provided witha double packing, resulting in the same being most effectively sealedagainst the passage of wind, dust and moisture, and as both pads aremounted on a single base, the device can be easily applied, withoutmakingy any changes or modifications in the wall or window casing.

The sheet metal base strip serves to hold the packing strips in properposition while thedbricks or other building blocks are being lai Iclaim: j

A weather strip comprising a flat rigid base strip having a bend in vthedirection of its length to form a lateral outstanding flange extendingthroughout the entire length of the strip, a packing strip attached tothe longitudinal edge of the base strip and covering the face thereoffrom which the flange projects, and a packing strip attached to theextremity of the aforesaid flange, said last-mentioned packing stripbeing offset relative to the first-mentioned packing strip and locatedin advance thereof.

In testimony whereof I aliix my signature.

CHARLES H. STARK.
